And yet I was mowing fools with my axe I had set at 160 psi....
185 is not enough pressure for the bolt to fully cycle.
Was ur 160 psi axe smooth?
Axes are smooth in general.
Don't put the output pressure from your tank higher than 200. I don't know why but Empire/Kee says so.
That would be the output from the regulator on the gun, not the tank regulator. An Axe will work fine on a standard output tank. You don't want to turn the regulator on the gun past 200psi.
